Abstract
A bis(phosphonate) conjugate of 2'-O-methyl oligoribonucleotide (microRNA-21) was synthesized and used as a bone-targeting carrier in the systemic delivery of a Ga-68-1,4,7-triazacyclononane-1,4,7-triacetic acid (NOTA)chelated 2'-O-methyl oligoribonucleotide (anti-microRNA-21). The whole-body biodistribution of the double helical RNA was monitored by positron emission tomography (PET), which verified the expected bis(phosphonate)-induced bone accumulation in healthy rats.
